Application filed April 29, 1926. Serial No. 105,595.

This invention relates to improvements in 'electrical condensers; particularly electrical .coidensers which are to be enclosed in a housing and to be connected to a cirguit exterior to said housing.

An object of the invention is to provide an electrical condenser with a housing therefor, and terminals to project through 'the housing and enable the condenser to be connected in a circuit in which it isto operate,

and to devise for this purpose a constructlonwhich is simple, easy, and cheap to make, and yet quite eiiicient in practice.

The drawings disclose the best form of my invention now known to me, but I may,

of course resort to variations not illustrated herein without departing from the spirit of my invention, or exceeding the scope of the appended claims.

. v On the drawings:

Fitgure 1 is a vperspective view of a housing or a' condenser according to my invention. c Figure 2 is a longitudinal sectional view of such a housing;

" -Figure.3 is a pers ctive view of asu porting plate throng which the termma s of the condenser project, and

Fig. '4 is' a cross-sectional view of the 80 housing-with an end view of the condenser The same numerals identify-the same parts throughout.

The numeral 1 indicates the body of the condenser that may beV of the type known as a rolled condenser made up of layers in the form' of .sheetsor strips of thin metal foil separated by insulation and wound up yin the fordm of a roll which can be more or less flattened if desired, one of the conductive strips or elements of this condenser has the edges of the turns thereof shown*` as projecting. from one end o f the body, as indicated at 2; 'andthe other element of opposite polarity hasits turns shown as prcjectlng :at-their the opposite endof the bod askin venelvosedffin a housing or case 4. This housing is o p n at the bottomand has Va closed t0p.wit openings ,5 and l6 through which enser. .fone-of these terminals is attached to each of the elements 2 and 3 of o poste polarity, and between-the body "of t ef conat 3, and the condenser. is

ing through the apertures 10 of the strip 9,

is then disposed against the inner surface of the top of the casing 4, so that the tabs 7'- and 8 project throlh the openings 5 and 6 to the extent requir but to gain this result, tle'casing 4 may be inverted so that the strip 9 will lie a ainst the inside of the surface of the top o the casing; and then the whole condenser may be embedded in wax by pouring wax into the casing 4 until the casingA is filled. When the wax cools and solidities, it will adhere to the inside of the surfaces of the casing and prevent the condenser 1 from fallinglout even when the top .is turned up and t e open bottom turned down. The condenser can thenbe mounted in any desired position on a panel or other support, and

for this purpose it is provided with projections `11 at its opposite ends in which'are openings 12 to receivefsuitable fastening means.

The Yinner ends of theterminal, tabs 7 `and 8 are swaged so that these inner ends. can be soldered .to advantage. to the elementsl 2 and 3; and the stri 9. of insulation when the casingisinverte through the holes 5 and 6,. This strip also to be ueawitt wax,.- serves -1 to prevent thewaxnzfrom flowing positionsfthe condenser in the middle of the casing-4,' holding it awa from the sides and ends of the-casing w en this casing is filledwith wax, and making a lining ltlnr n e the interior of the box or container. box 4 is enerally ofmetal, such astin,'and

the openings 5 and 6 are largeenough te .clear the projecting ends of thetabs 7 and 8so that thefed ves of' these openings udo.

not ltouch -these ta s.\ Hence the condenser is well housed i'n a stro 'and the two terminals \are always discon` nect'ed, and 'nofdanger of *shortgshort circuiting exists;

Having described invention, what lng metal container,

,at each endV thereof.

believe'to be new anddesire to secure and protect by Let/ters Patent of the United States is A 1. A condenser comprising, a rolled body, a casing in which the body is disposed, the casing having openings adjacent opposite ends of the body, a terminal in the form of a flat relatively wide strip secured'to each of the opposite ends of-the body, the terminals projecting through said openings, an insulating embedment sealing the condenser in the casing, and perforated metallic lugs carried. by the casing, and projecting one 2. A condenser/comprising a'rolled body,

ba casing in which'the body is disposed, the

casing having openings adjacentopposite ends of the body, a strip in the casing extending fr'om end to endof same over said openings, a terminal in the form of a fiat relatively wide strip secured to each of the i opposite ends of the body, the terminals projecting through said strip and said openings van insulating embedment sealing the condenser -in the casing, and 4perforated metallic lugs forming a part of the casing, and projecting one at each end' thereof.

3. A condenserl comprising-a rolled body,

a :metalliccasing n'whch the body is disto each of the opposite ends of the body and projecting through said open-ings, an insulating embedment sealing the condenser in the casing and filling the casing between the top and bottom thereof, and perforated metallic lugscarried by the casing and projecting one at each end thereof.

4. A condenser comprising a rolled body, a metallic casing in 'which the body is disposed, the-casing being closed at the top, sides and' ends, but open at the bottom, and having lopenings at -the top adjacent the opposite ends of the body, a strip in the'casing extending from end to end of same over said openings, terminals ysecuredl to each of the opposite ends of the body and projecting through said strip and said openings, an insulating embedment sealing the condenser in the casingfandilling the condenser between top and bottom, and perforated metallic lugs carried b the casingand projecting each at one end thereof.

In testimony whereof I affix my signature.
